摘要
The electronic structure and magnetic ordering in La1-xPrxCo2P2 (x = 0,0.25, and 1) phosphides have been studied theoretically using the fully relativistic spin-polarized Dirac linear muffin-tin orbital (LMTO) band-structure method. The X-ray absorption and X-ray magnetic circular dichroism spectra at the CoL2,3 and PrM4,5 edges have been investigated theoretically within the framework of the LSDA+U method. The core-hole effect in the final state as well as the effects of the electric quadrupole E-2 and magnetic dipole M-1 transitions have been investigated. Good agreement with experimental measurements has been found.
